We have had our new Intex Ultra Frame 16' x 48" pool up for about 3 weeks, and so far all of our water tests have been good and the water is clear. We have been running the saltwater chlorinator for about 4 hours each day, and I have noticed that towards the end of each chlorination cycle (maybe for about the last half hour) that the chlorinator does not seem to be producing any more chlorine (i.e. can't see any bubbles being formed in the clear tube). It doesn't seem to matter what amount of time we set the chlorinator to run (2, 4 8 hours) it always seems to stop producing chlorine towards the end of the cycle. Is this normal, or is there something wrong with the SWG? Our salt level is about 3200 ppm, and we consistently get a FC reading of about 2 ppm. Has anyone else observed this with their Intex Krystal Clear SWG?
